Steps to reproduce:
I host two identical sites locally - one is at localhost:80 and the other is at localhost:8000. They have the following content:
<html><body>Hello World <script src="http://www.google.com/jsapi"></script></body></html>
They have identical CSP headers:
x-content-security-policy:allow 'self'; script-src www.google.com;
Actual results:
The site at localhost:8000 does not load the script from google and raises the following error:
Warning: CSP: Directive "script-src www.google.com" violated by http://www.google.com/jsapi
Expected results:
I would assume both sites should behave the same. I can see how different ports may affect the patterns in the CSP headers, but not the site that contains the CSP headers.

fix
I created an xpcom test that quickly verified this behavior.
The fix itself is pretty straightforward (bad logic), but there were some other bits of the parser that needed repairs as a result of this fix to keep our unit tests happy. These were deep problems in the way that 'self' was being parsed and handled, and as a result, I had to rework some of the 'self' parsing and object representation to do the right thing (act as a pointer to another CSPSource).

I was just about to rebase this patch, but it looks like there's no merging necessary. It still applies cleanly to mozilla-central. We should probably land this, since it's tiny and has been sitting with r+ for many moons.
